Synthesis of 4-substituted 3-methyl-1-phenyl-2-pyrazoline-5-thiones by heterocycles

4-bromo-3-methyl-1-phenyl-2-pyrazoline-5-thiones was reacted with the sodium salt of some reactive methylene compounds and then condensed with hydrazine hydrate, phenylhydrazine, hydroxylamine hydrochloride, urea and thiourea to obtain 4-substituted 3-met
